Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin. In particular, a method of densifying a fibrous composition is disclosed, the method comprising: shearing a fiber source to provide a fibrous material; combining the fibrous material with a microorganism and/or enzyme to provide a fibrous material composition; encapsulating the composition in a substantially gas impermeable material; and removing entrapped gas from the encapsulated composition to densify the composition. |
